She's praying to Virgin of Guadalupe that she doesn't get kicked out of her Richmond, Virginia, mobile-home park.
Sanchez made her money searching for and recycling scrap metal and selling tamales in a heavily Hispanic neighborhood. Fear of getting sick has stopped both income streams. A single mother of two who immigrated from Honduras to the U. She hasn't heard from the landlord about what will happen if the rent isn't paid. So she keeps praying. But the popular Nashville restaurant closed its dining area, and working as a sommelier isn't something Larson can do from home.
Larson said she was humiliated but applied for food stamps. Larson, 42, moved from a high-rise downtown apartment to a house in east Nashville four months ago.
Rent was cheaper. She planned to pay off debt and start saving. Instead, she called credit-card companies and said she couldn't pay the minimum. Larson's restaurant offered a few shifts answering phones for takeout, but she figures it's not worth the risk of getting COVID But the rent comes due again in 30 days. Can she afford a smaller apartment in her building if one's available? Should she move in with friends if they'll let her?
Before being laid off, she made drinks and chatted with people from around the world for 20 years as a bartender at the Palmer House Hilton Hotel in the heart of Chicago's downtown Loop.
Now, she's on unemployment for the first time and searching for work. Tnia Morgan shares her Baltimore County, Maryland, townhouse with her year-old pregnant daughter and year-old nephew.
And they all spend a lot more time together since Morgan was laid off March 6 from her job serving food at a hotel banquet hall.
Morgan's landlord told her to take her time with the rent. But it isn't the only bill piling up. She ticks them off — car payment, car insurance, cellphone, internet, water, gas and electricity. And she always has to buy food, so tough choices are ahead, especially until unemployment benefits kick in. Morgan, 39, has checked on getting food stamps and looked for work at stores and warehouses with no luck.
She appreciates her landlord's kindness this month. But she knows he needs her rent money to pay his bills.
Bartender Luke Blaine was laid off when downtown Phoenix restaurant Fez closed, but he's not too worried about rent — yet. He shares his small adobe-style home and backyard garden of tomatoes, beets, squash, radish, lettuce and eggplants with his boyfriend, Kyle Schomer.
Schomer still has his job in technology and works from home. Blaine, 30, figures unemployment will kick in. His car is paid for, and he owes little beyond a small credit-card balance. Blaine credits his thrifty nature to his family. And that's whom he worries about most these days. His mother and sister are nurses in Illinois, not far from hard-hit Chicago. She was going to college and was a part-time cafe cashier. She couldn't wait for the Special Olympics in March, to run and compete in long jump and shot put.
But the virus closed the cafe, canceled the meet and ended the community college's personal instruction. Bailey, 30, of St. Louis County, was dipping into savings for food and other necessities, so she's moved back in with her mother. Jason W. Still was let go from his job as a cook, and he's found one small benefit: He hasn't spent as much money since he's inside most days. Still and his wife — who works in packaging for a marijuana dispenser in Spokane, Washington — should be able to make April's rent as they wait to see what he'll get in unemployment and from the federal government.
Still, 30, worked at a high-end restaurant and just finished the last classes for his bachelor's degree. Now he's applying for graduate school to study environmental economics and public policy. It's a lousy choice, but an easy one for personal trainer and apparel designer Sakai Harrison — food in the refrigerator over April rent for his Brooklyn apartment.
